TOBQUE CONVEMER SETSCREWS
(.All Au tome.. tic Transmission Models)
Torque converters are DDW secured to the drive plate with longer setscrews (Part number 0.16682). To ensure f'ul.l engagement of' the longer thread, a cut-a.1ay is machined in the torque converter below each threaded hole as indica. ted by the arrow in Fig. 2.
Note that it is ABSOLUTELY ESSENTIAL that the lone; setscrews whiah are 17/32" (13.5 Dm) in length (see inset in Fig.2.) are not fitted to a torque converter which does DOt h4ve cut-a-ways--macbined under the setscrew boles, otherwise the setscrews will bottom in the holes. A torque converter Wi.tlx>ut the out-a"""WB;y is illuatra.ted in Fig.1 ; the 7/16" ( 11 .1 um) l ong setscrew which wsr be fitted to this type of converter is shown inset.
In fu.ture, all converters supplied from Jaguar Spares Division will have the correct setscrews attached.

DELETION OF MULTIPLE DISC CLUTCH BLEED VALVE
(All Automatic Transmission Yodels)
With effect from November, 1960 the bleed valve at the bottom of the multiple disc clutch cylinder in the low drum is omitted.
The omission of the bleed valve does not affect the operation of the transmission. The two types of front sun gear and low drum assemblies with and without bleed valve are therefore interchangeable and the part number is unchanged.

WARRANTY - BORG-WARNER TRANSMISS ION AND CONVERTER UNITS
Distributors and Dealers will be aware that to date warranty for Borg-Warner converters and transmission units has been limited by Borg-Warner Limited to s i x months or 6,000 miles, but concessions have, in fact, been given beyond this specified period in line with the standard six months warranty given by Jaguar Cars Limited.
Please note that by agreement with Borg-Warner Limited as from the lst July, 1961 it will be possible to provide improved warranty conditions for Borg-Warner converters and transmissions, for which similar warranty to that covering Jaguar cars will be given, with the exception that warranty terms will be extended where trouble is experienced with a converter or transmission unit on a car over six months but not exceeding 12 months old, providing the mileage does ndt exceed 12,000.

KAINSHAFT RECONDITIONING SERVICE
(All models fitted with Automatic Transmission)
A reconditioning scheme for Automatic Transmission mainshafts has been introduced.
This scheme will apply only to those Mainshafts in which the Lubricating Valve has become inoperative, this being the usual reason for changing the Yainshaft. To qualify for the special exchange price applying to the scheme, all returned Mainshafts must satisfy the following conditions.
(1) An inoperative Lubricating Valve shall be the only qualification for a Mainshaft to participate in the reconditioning scheme.
(2) Mainshafts must be free from rust and undamaged externally. Damage caused to a displaced shaft whilst in transit wi l l result in the reconditioned Shaft being charged at full retail price. It is therefore recommended that the displaced Mainshaft shall be returned in the package in which the reconditioned Shaft was supplied,
Reconditioned Mainshafts are obtainable from Jaguar Spares Division to Part Number 3631/R. When a reconditioned Mainshaft is ordered, it will initially be charged at the full retail price of £15 pending the return of the displaced Shaft and subsequent notification by the manufacturers of its suitability for reconditioning. Immediately such notification is received, a Credit Note will be issued to adjust the initial charge to the exchange price of £2. 10. 6d.

SERVO CYLINDER SEALING RING
On all Borg Warner automatic transmission units now being fitted to current production models, a copper sealing ring (Part No. 9204) is fitted to the servo cylinder bolts. The sealing ring is to prevent oil seepage along the threads of the bolts and is fitted between the spring washer and the servo cylinder. The side of the washer with the smaller hole is fitted against the spring washer.

SELECTING P (PARK) WHEN REVERSING
WARNING
(All Automatic Transmission Models)
It is pointed out that, due to the reverse rotation of the rear pump, the parking pawl hydraulic interlock does not operate in R (Reverse).
It is, therefore, ESSENTIAL that the P (Park) position is not selected whilst the car is movi ng in Reverse other,.;ise the parking pawl may be broken off. Always bring the car to a stop and apply the hand~rake firmly before selecting P.
Will Distributors and Dealers please bring this matter to the notice of owners who have automatic transmission models.

STICKING FORWARD SERVO
Attent i.on is aga1n drawn to the following symptoms of a stic!<.ing forward servo,as cases have come to our notice of incorrect diagnosis of this trouble.
1. Car drives forward inN (Neut ral).
2. Transmission drags in R(Reverse).
Normal operation in D (Drive) and L (Low) positions.
Action
If the cause or the servo sticking i s due to mal-alignment this can be rectified by slackening t he nine low and forward servo cylinder securing bolts slightly, removing the pressure takeoff plug from the forward servo and operating the servo a few times by means of a thtn rod inserted through the pressure takeoff hole.
The servo cylinder bolts should then be tightened to a torque of 15 to 18 lbs ft. (2.07 to 2.48 kgm} and the pressure take-off plug replaced.
If this procedure does not effect a cure ,the low and f orward servo cylinde r should be removed and if there a re no burrs or ragged edges on the outside diameter of the forward servo pis ton the low and f orwa rd servo assembly should be changed .

REAR BAND AUJUSTh1EJYI'
Revised f i.gures are now advised for rear band adjustment for the Model 35 range of Automatic Transmiss ion Units fitted wj th tile 7/16" (11.1 mm.) diru;1eter adjusting screws as follows:-
(1) Slacken the locknut and tighten the band adjusting screw to a torque of lOlb./ft. (1.38 kg.m.), using a torque wrench and an adaptor.
(2) Back off the adjusting screw~ to !s of ' turn and, ho.lding the adjusting screw, ti.ghten the locknut with a box spanner.
NOTE: These revjsed figures do NOT apply to the early model 35 Transmission unit with the smaller diameter adjusting screw.
Jaguar Cars Limited 2005
Bulletin FF. 21 July, 1968 Page 2 of 2
When the rear clutch is stripped, the clutch piston spring seat should be checked and if the two faces are not in line within . 02011
( .508 nun.) should be discarded and replaced with a part that is correct to drawing.
This may be obtained from JAGUAR SPARES DIVTSION, COVENTRY, under Part Number 9806.
Due to tolerance stack-ups, it is extremely unlikely that this fault would become apparent on transmissions having 3 or 4 plate rear clutches. However, if such a unit is being stripped for any reason, this part should be checked and replaced if required.
IT IS EMPHASISED THAT 1HERE IS NO SAFETY PROBLEM involved in this fault, and that this bulletin is issued to assist Di stributors and Dealers in the diagnosis of any unusual rear clutch failures which may occur.

The new fluid has improved frictional characteristics and is ap})roved for use in all Automatic Transmission and Power Assisted Steering Units fitted to Jaguar cars. The new fluid is miscible with the previous Type A Suffix A brand and it Will therefore not be necessary to drain units when topping up becomes necessary. It is, o~ course , preferred that the new M2C 33R fluid should be used whenever possible.
